The US is definitely in a post-Christian era. Europe has been there for a long time. Christianity is growing in China. Those with a post-millennial eschatology see the church as ushering in a golden age before Christ's return, but I still subscribe to the premillennial view that we are heading to a time when less folks will care and, as in the days of Noah, folks won't see the judgment coming until its too late.
